Contact tracers will ask you a series of questions to help you remember with whom you may have contacted while you were contagious. They may ask where you work, where you have been, where you obtained food or other supplies, and with whom you visited. The more detail and honesty you can provide, the better the investigation.
Confidentiality is always maintained during this process. Contact tracers will never ask for Social Security Numbers, financial information or other unnecessary personal details.
